【摘要】 本文针对建筑物的手工测量人工流程复杂，测量独立误差的问题，提出一种基于建筑信息模型(Building Information Model, BIM)和原始点云的快速匹配方法。首先，提取BIM和原始测量点云的平面模型；然后，分别选择其中的四个平面，采用暴力匹配的方法，求解全等匹配平面集合，实现BIM和原始点云模型的匹配功能。结果表明：该算法能实现BIM模型和建筑点云模型匹配功能，可作为监测建筑过程的辅助手段和监测建筑物健康程度的依据。更多还原

【Abstract】 In this paper, a fast matching method based on Building Information Model(BIM) and original point cloud is proposed to solve the problems of complex manual measurement process and independent measurement errors.Firstly, the plane model of BIM and the original measurement point cloud is extracted.Then, four of the planes are selected respectively, and the force matching method is used to solve the uniform matching plane set, and the matching function of BIM and the original point cloud model is realized.The results show that the algorithm can realize the matching function of BIM model and building point cloud model, and can be used as an auxiliary means to monitor the construction process and the basis for monitoring the health degree of buildings.更多还原
